Nutri-Mastic™ with Mastic Gum blend. The normal gastrointestinal tract contains the most toxic environment to which most people are ever exposed. From the mouth to the anus, every centimeter is colonized by bacteria, with the colon bearing the greatest load. Scavenge ammonia (toxicity) that has not been incorporated into urea makes it impossible for probiotics to reach its desired area (the colon) People on the autistic spectrum generally do not colonize intestinal flora easily, and their digestive systems tend to fall out of balance very easily. Nutri-Mastic™ lessens scavenge ammonia, which is critically important for digestive health, to help grow probiotics in the intestines.
